Lid and a container assembly having the lid

ABSTRACT

Provided is a lid having a lid body and multiple ribs. The lid body has an extending portion and a connecting portion connected with the extending portion. The extending portion is formed with an opening at one end distal to the connecting portion. The connecting portion protrudes outwardly along the lid&#39;s radial direction, and one end of the connecting portion distal to the extending portion dents inwardly to form an annular containing space. Multiple ribs are formed protruding on where the extending portion is adjacent to the connecting portion. Also provided is a container assembly including the lid and a cup body having a cup rim. With one end of the connecting portion distal to the extending portion continuously denting toward inside of the lid body, the cup rim and the connecting portion can be tightly engaged.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a lid, especially a lid having a connecting portion and multiple ribs, and the present invention also relates to a container assembly having the lid and a cup body.

2. Description of the Prior Arts

At present there are a lot of beverages on the market, the beverage types vary from coffee to black tea and even smoothies, so disposable beverage cups have become one of the items people frequently use and carry around them.

Please refer to FIG. 7 and FIG. 8. The conventional beverage cup has a cup 80 and a lid 90, the lid 90 having an arced cover 91, a covering portion 92 and a prolonging portion 93 connected in order; wherein the covering portion 92 protrudes outwardly along the lid 90's radial direction, and in order to make the lid 90 easy to cover the lid rim, one side of the prolonging portion 93 adjacent to the covering portion 92 dents at spaced intervals along the radial direction of the lid 90. However, the smoothies contained in the cup usually exceed the cup rim to inside of the lid 90, and when the smoothies are melted or the cup 80 tilts, causing liquid to exceed the cup rim, the liquid would be spilled from the portion that is not concave in the prolonging portion 93. Besides, the users usually hold the cup 80 in one hand and take the uppermost lid 90 from the multiple stacked lids 90 by the other hand when serving drinks, however, the stacked arced covers 91 in the conventional beverage cup easily tilt and fall, so it is difficult to take the uppermost lid 90 when the lids 90 are stacked.

For this reason, how to develop a cup lid that is unlikely to leak when engaged to the cup, and is easy to pick up when stacked, the current technique needs to be further improved.

SUMMARY OF THE INVENTION

To overcome the shortcomings, the object of the present invention is to provide a lid which can be engaged to a cup tightly and is easy to pick up when stacked.

To achieve the aforementioned objective of the present invention, the present invention provides a lid comprising a lid body and multiple ribs. The lid body contains an extending portion and a connecting portion connected with the extending portion. The extending portion is formed with an opening at one end distal to the connecting portion. The connecting portion protrudes outwardly along the lid body's radial direction, and one end of the connecting portion distal to the extending portion dents radially and inwardly to form an annular containing space. The multiple ribs are formed protruding on where the extending portion is adjacent to the connecting portion.

Preferably, the peripheral edge of the radial cross-section of the extending portion is tapered toward the opening.

Preferably, the radial cross-section of the lid body is round.

Preferably, the lid body further has a guide portion which is connected to one end of the connecting portion distal to the extending portion, and the guide portion is in the shape of an annular plate.

Preferably, the number of the ribs is eight, and the ribs are spaced apart from each other.

The present invention also provides a container assembly having the lid of the present invention and a cup body, and the cup body has a cup rim, which is set on the connecting portion of the lid body and contained in the annular containing space.

The present invention has the advantage that the lid is easy to pick up. When multiple lids are stacked, the upper lid is spaced apart from the lower lid by the ribs, and thus the lids can keep stacking upward without being tilted at the same time; with the connecting portion continuously denting toward the inside of the lid body at one end distal to the extending portion, the cup rim and the connecting portion can be tightly engaged to avoid leakage of the liquid in the cup body due to inclination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, the technical means in accordance with the present invention for achieving the foresaid objectives are illustrated from the following figures and preferable examples.

Please refer to FIG. 1. A lid of the present invention comprises a lid body 10 and multiple ribs 20. In one preferred embodiment, the radial cross-section of the lid body 10 is round.

Please refer to FIG. 1 to FIG. 3. The lid body 10 contains an extending portion 11, a connecting portion 12 and a guide portion 13. The extending portion 11 is formed with an opening 111 at one end distal to the connecting portion 12. In one preferred embodiment, the peripheral edge of the radial cross section of the extending portion 11 is tapered toward the opening. 111. The connecting portion 12 protrudes outwardly along a radial direction of the lid body 10. One end of the connecting portion 12 is connected with the extending portion 11, and the other end of the connecting portion 12 dents radially and inwardly to form an annular containing space 121.

The multiple ribs 20 are formed protruding on where the extending portion 11 is adjacent to the connecting portion 12. In one preferred embodiment, the number of the ribs 20 is eight, and the ribs 20 are spaced apart from each other.

Please refer to FIG. 4. The lids of the present invention can be stacked with each other. The lower rib 20 abuts against the inner side of its upper rib 20 to reduce the storage space and to keep stacking upward without tilting at the same time. As the upper lid is spaced apart from the lower lid by the ribs 20, it would not be difficult to pick up the upper lid due to the negative pressure caused by the close abutment between the upper and the lower lids, and thus the user can pick up the upper lid easily.

Please refer to FIG. 5 and FIG. 6. A container assembly has the lid of the present invention and a cup body 30. The cup body 30 has a cup rim 31, which is set on the connecting portion 12 of the lid body 10 and contained in the annular containing space 121.

When the container assembly of the present invention is in use, the lid is set on the cup rim 31, with the connecting portion 12 continuously denting toward the inside of the lid body 10 at one end of the connecting portion 12 that is distal to the extending portion 11, the cup rim 31 and the connecting portion 12 can be tightly engaged and firmly placed inside the annular containing space 121, and even when the liquid in the cup body 30 exceeds the cup rim 31, it would not be leaking from the junction between the cup rim 31 and the connecting portion 12.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
